Rotatable Hook Assembly

ABSTRACT

A rotatable hook assembly is disclosed, which has a twist handle rotationally coupled to a bag hook for holding bag handles. The assembly may have a lockable attachment such as a cup holder.

This nonprovisional claims the benefit of and incorporates by reference Appln No. 62/503,891, which was filed on May 9, 2017.

BACKGROUND OF THE INVENTION 1. The Field of the Invention

The present invention relates generally to the field of convenience carry articles such as bags, sacks, etc.; more specifically, to that of devices for organizing and handling convenience carry articles; and more specifically still, to a rotatable hook assembly for organizing and handling convenience carry bags.

2. Background

Not so many years ago, when a person went shopping at a grocery store or other store, articles that were purchased were placed in boxes, paper sacks, and/or wrapped in bundles for transport home. In more recent times, purchases are placed either in plastic “store bags” or re-usable bags for transport. In either case, handling such bags can be cumbersome and keeping them closed and organized often is challenging.

To address this problem, people may utilize a large carabiner to gather the handles to all their bags. This keeps the bags somewhat organized, but usually has limited space that quickly fills when multiple bag handles are gathered together. Further, the carabiner can't keep bags suspended upright, and can be difficult to attach to shopping carts, headrests, etc.

A need exists for an organizing device that may be useful for storing plastic bags, is easily usable, and can be easily stored so as not to be lost. Additionally, if the organizing device has additional functions, then that would be desirable.

BRIEF DESCRIPTION OF THE DRAWINGS Brief Summary of the Invention

The rotatable hook assembly 10 is designed to meet all of the above criteria and more. It can comprise five or more primary components: a locking twist handle, a bag hook, a suspension thickness buffer, a lock in accessory, and a headrest storage hook. The locking twist handle functions in concert with the bag hook to form the main body of the rotatable hook assembly 10. Together, they provide for a hook on which a plethora of shopping bag handles (or similar) can be gathered and hooked as well as a locking member which, once activated, secures the handles on the hook. The locking twist handle also comprises a convenient carry handle so that multiple bags can be carried simultaneously by the user in one hand without discomfort, pinching, and other common issues experienced when carrying multiple bags with a bare hand. The twist function allows the locking twist handle to twist open and closed making adding and/or removing bags from the bag hook a simple process. The bag hook can incorporate a first cart member to hang the device from the sidewall of a shopping cart or similar relatively thin, vertical surface. Additionally, a suspension thickness buffer helps the first cart member work for various thicknesses of vertical surfaces by adjusting to fill the void spaces between the first cart member's sides and the vertical surface placed therebetween. An additional lock in accessory can be incorporated into the rotatable hook assembly 10 as well. In one embodiment, this comprises a lock in cup holder that snaps into a groove in the bag hook's exterior and is locked in place by the closing of the twist handle. Optionally attaching to the twist handle can be a headrest storage hook which allows the rotatable hook assembly 10 to be attached to and hang from a vertical tube or support member of an automobile's headrest.

Referring to 14B; an embodiment of an entrapment bay is shown; the button shaft 700 is depicted in cross section. Referring to FIG. 20A a button shaft is shown; button shaft 700 may have a button 702, which may be substantially conical or round or thimble-shaped. Button shaft 700 may have a button support 704, which may be substantially similar in shape to button 702; in some preferred embodiments the button support 704 has a front flat surface and is coupled to the back of the button; button shaft 700 may have a main body 706; the main body 706 may have substantially flat surfaces; the main body 706 may have one or more angled portions 708 a, 708 b; the rear portion of the main body 706 may have a button shaft wedge 709; the button shaft wedge may have an angled back portion 710 and a substantially vertically aligned front portion 712. In 14B a gap is shown between the shaft and the locking portion so that in the preferred embodiments the contour of the locking portion is such that it is in frictional contact with the button shaft wedge and help in place by the button shaft wedge.

Referring to the button shell 800, a centrally positioned button member 802 may be substantially circular or round and may define a void that is large enough for button 702 to protrude from. Half of a button shell 800 is shown in FIG. 700 due to being a cross sectional view; button shell 800 may have a first button support member 804 which may be frictionally coupled to the button support 704 and a second button support member 806 which may also be fictionally coupled to the button support 704. The first button support member 804 may have a first lip 810, and the second button support member 806 may have a second lip 812. The button shell 800 may have a front chamber defining member 814 which defines a chamber for the button 702; the front chamber defining member 814 may be circular or substantially circular in shape; button shell 800 may have an upper left face 820, an upper right face 822, a lower left face 824, and a lower right face 826. When a user presses on one or more of the upper left face 820, an upper right face 822, a lower left face 824, and a lower right face 826 of the button shell 800, the button shell engages the button support at either the first lip or the second lip, thereby pushing the button shaft backwards such that the button shaft wedge 709 no longer locks the locking portion 202 in place such that the locking portion 202 is free to be rotated counterclockwise or clockwise such that the bag hook 200 may be rotated open thereby allowing access to the bag storage loop. In some embodiments, a user may press on the button 700 such that the button 700 exerts pressure on the button support 704, and the button shaft is moved backwards thereby disengaging the button shaft wedge 709 from the locking portion 202 of the bag hook 200. In some embodiments, a coil, spring 900, or spring member may be positioned in a chamber defined by the back portion of the button shell and the twist handle; the corners of the cross sectional depiction of the chamber are depicted by the portions 831 a (of the button shell), 831 b (of the button shell), 831 c (of the twist handle), and 831 d (of the twist handle). The spring 900 may be useful for returning the button shell to its starting position after the button shell has been moved to the rightward direction (with respect to FIG. 14b ) When the button shell is returned to its original position by the decompression of the spring 900, the original position being shown in FIG. 14B, then the button shaft wedge may be brought closer or sufficiently close to the locking portion 202 in which the button shell may be frictionally engaged with the button shaft wedge. The spring 900 may be coupled around a portion of the main body of the button shaft and may be partly coiled so as to be disposed inside of a portion of the button shell.

Referring to FIG. 22; the suspension buffer may have one or more back band members 906, 908 which may be used to rest upon one or more back band member ridges 260 a of the bag hook 200; a distal back band member ridge 260 a is depicted in FIG. 19A as also a proximal back band member ridge 262 a; however some embodiments have a second distal back band member ridge located from the first distal back band member ridge at a distance substantially equal to the distance between the two back bands; and some embodiments have a second proximal back band member ridge located at a distance from the first proximal back band member ridge at a distance substantially equal to the distance between the two back bands.

In the following discussion, numerous specific details are set forth to provide a thorough understanding of the present disclosure. However, those skilled in the art will appreciate that embodiments may be practiced without such specific details. Furthermore, lists and/or examples are often provided and should be interpreted as exemplary only and in no way limiting embodiments to only those examples. Similarly, in this disclosure, language such as “could, should, may, might, must, have to, can, would, need to, is, is not”, etc. and all such similar language shall be considered interchangeable whenever possible such that the scope of the invention is not unduly limited. For example, a comment such as: “item X is used” can be interpreted to read “item X may be used”.

FIG. 1 introduces a rear perspective view of an exemplary embodiment of a rotatable hook assembly 10 with a number of sub-components depicted with reference numbers. The rotatable hook assembly 10 embodiment in FIG. 1 may have a twist handle 100 which may be configured to be locked. The twist handle 100 may have an entrapment bay 110 to entrap and hold a locking portion 202 (see FIG. 1A) of the bag hook 200, thereby ensuring that any bag handles that have been threaded through the bag hook 200 are trapped thereon and generally cannot be removed from an area defined above by the twist handle 100 and below by the bag hook 200 without unlocking the bag hook 200 from the twist handle 100 and purposefully removing a bag or by ripping open the handle of a bag so as to create an opening. The entrapment bay 110 may incorporate a lock flange 120 to define a locking area for locking the bag hook 200 into the entrapment bay 110.

Extending upwards from the entrapment bay 110 may be a grasp handle 102. grasp handle 102 may be arcuate. grasp handle 102 may provide a grasping surface so that a user can wrap the user's hand around the grasp handle 102 and carry the rotatable hook assembly 10 as well as all the bags suspended therefrom without the pinching and discomfort commonly experienced when attempting to carry multiple bags with a single handle.

The bag hook 200 may have a rotation bay 140 (see FIG. 12b ) having a rotatable member 204. In some preferred embodiments, rotatable member 204 may have a plurality of compressible prongs 208 a, 208 b, which may be inserted into the rotatable member receiver 206 of the bag hook 200. Each of the plurality of compressible prongs 208 a, 208 b may have an upper portion 210 and a lower head portion 212. The rotatable member receiver 206 may have a void member 209 which defines a void which is large enough to accommodate the plurality of compressible prongs 208 a, 208 b when the compressible prongs 208 a, 208 b are squeezed together, but the void may be not large enough to allow the lower head portion 212 of each of the compressible prongs 208 a, 208 b to be removed from the void defined by the void member 209 when the compressible prongs 208 a, 208 b are not compressed. In some preferred embodiments, rotatable member 204 may be a void that receives a fastener and an optional washer. See FIG. 7 of the provisional application from which this application claims a benefit.

In some preferred embodiments, an accessory lock 150 (see FIG. 1h ), which may have one or more protrusions, may extend downwards from grasp handle 102. Preferably located at the end of grasp handle 102, the twist handle 100 may be twisted clockwise or counterclockwise so as to lock an accessory, such as a cup holder, via accessory mount 430 into the accessory mount receiver 214 of bag hook 200.

When the twist handle 100 is twisted closed, the entrapment bay 110 may surround a portion of the bag hook 200 called the entrapment tooth 210. The locking portion 202 of bag hook 200 may extend upwards into the entrapment bay 110 and may include an entrapment tooth 210 which may be coupled by a slot defined by the lock flange 120 of twist handle 100 when the twist handle 100 is in the locked position, thereby ensuring that the bag hook 200 may not be rotated substantially clockwise or substantially counterclockwise until a user has lifted the entrapment tooth 210 above the slot of the lock flange 120. The bag hook 200 may comprise a locking portion 202 which may be positioned at the end of the bag hook 200 above a bag storage loop 230. The bag storage loop 230 may comprise the bulk of the bag hook as it loops from the entrapment tooth 210 down and around back up to the rotation member 240. The bag storage loop 230 can hold one or even a large number and variety of bag handles threaded thereon. Once the twist handle 100 is in a twisted closed position on the bag hook 200, the bags may be locked onto the bag storage loop 230 and may not be removed without again twisting the twist handle 100 to gain access to the bags on the bag storage loop 230.

The bag storage loop 230 may terminate into the rotation member 240. The rotation member 240 may be rotatably coupled with the rotation bay 140 and the two components may rotate relative to each other. Extending downwards from the other side of the rotation member 240 is the first cart member 250, which may have a substantially flat portion and may have a length greater than the average bar used in a grocery cart on which the first cart member may be placed in frictional contact. The first cart member 250 may be between 0.1 inches and 500 inches in length, may be between 0.1 inch and 5 inches in length, may be between, 1 inch and 2 inches in length, may be between 2 inches and 4 inches in length, may be between 4 inches and 6 inches in length, may be between 6 inches and 8 inches in length. The first cart member 250 extends downward from the main lateral portion of the bag hook 200 and is opposed to the second cart member 252, which may also extend downwards from the main lateral portion of the bag hook 200. As defined herein the second cart member 252 may be substantially the same length of the first cart member 250, and the first cart member 250 and the second cart member 252 may be substantially parallel to each other, or in some preferred embodiments, the first cart member 250 may be slightly angled downwards at an angle between 0.1 degrees and 30 degrees from a horizontal line, such that a shopping cart bar may be wedged between the first cart member 250 and the second cart member 252 and one of the first cart member 250 and the second cart member 252 may flex to allow the shopping cart bar to be inserted and then may flex back to at or near the original position so as to grasp or hold the shopping cart bar. In some embodiments the length between the first car member 250 and the second cart member 252 is between 15 mm to 23 mm, wherein the difference between the first cart member 250 and the second cart member 252 at the top of the first cart member compared to the bottom of the first cart member is between 0.1 mm and 3 mm, and in some preferred embodiments is between 1 mm and 2 mm.

When suspending the rotatable hook assembly 10 from shopping cart walls of varying types and thicknesses, a suspension thickness buffer 300 may be incorporated into the gap between the first cart member 250 and the second cart member 252. The buffer may be compressible or otherwise deformable so that it can fill any excess gap left after the rotatable hook assembly 10 is hung from a shopping cart wall. Further, in the case of relatively thick sidewalls, it needs to squeeze down and provide more space for the sidewall in the gap. In order to function in this way in some embodiments, the buffer 300 man comprise a plurality of thickness adjusters, which may be the pieces that define channels of the suspension buffer also known as the suspension thickness buffer 300. Extending from a side of the first cart member 250 opposite the gap in which the shopping cart sidewall can be placed, may be an optional lock in accessory 400. In the embodiment illustrated in FIG. 1, the lock in accessory is a cup holder; other lock in accessories are contemplated (such as a cell phone holder, shelf for a wallet, etc.). The cup holder lock in accessory 400 can utilize a top edge cup holding lip 410 that provides a support surface to strengthen the cup holder and support a cup placed therein. At the bottom edge may be a reduced diameter ring 420 which squeezes down the diameter and so allows the cup holder to firmly grasp a cup placed therein.

A headrest storage hook 500 may be included; the headrest storage hook 500 may have a first arcuate portion and a second arcuate portion. The first arcuate portion may be substantially perpendicular to the second arcuate portion. storage hook 500 can be hooked around a headrest upright support member or other object so that the rotatable hook assembly 10 can be used in the car or anywhere a loop or hook receiver is located; thus, storage hook 500 is not just limited to use on the sidewall of a shopping cart.

FIG. 1E illustrates a rear elevation view of an exemplary embodiment of a rotatable hook assembly 10. In this view additional structural components of the headrest storage hook 500 are visible. For example, the storage hook extension 510 is shown extending from the storage hook attachment 520 to the headrest catch 530. The hook extension provides additional room between the catch and hook attachment so that the rotatable hook assembly 10 can rest somewhat vertically against the seat. The suspension buffer may be made from silicone, rubber, or any other flexible material.

FIG. 1F illustrates a top plan view of an exemplary embodiment of a rotatable hook assembly 10. This Figure provides an additional perspective on the rotatable hook assembly 10 such that the headrest storage hook 500 and cup holder lock in accessory 400 can be more clearly discerned. Additionally, it should be apparent that the headrest storage hook 500 is removable from the twist handle 100 simply by snapping the headrest hook attachment 520 off from around the handle 100.

FIG. 1G illustrates a bottom plan view of an exemplary embodiment of a rotatable hook assembly 10 which shows additional detail of the suspension thickness buffer 300, including the thickness adjusters 310 which are also described as pieces which define vertical or horizontal channels. FIG. 1H illustrates an exploded view of the various components of an exemplary embodiment of a rotatable hook assembly 10. Here, the various major components have been exploded out from one another so that their various shapes and functions can be more clearly discerned. In some embodiments there are a shown a plurality of thickness adjusters 310 on the suspension thickness buffer 300.
